Some men (especially of the manosphere variety) will tell you that men are simple creatures, they just want a chick who is hot and submissive and not a single mom.

No, men are complex just like women. Sometimes, being hot and submissive is not enough. Here´s an example from real life:

My coworker (35M) married his highschool sweetheart (35F) some years ago. They were together since they were 16 or something. I think he was her only relationship too. She was NOT a career woman, in fact he would often complain about how unambitious she is. I think she only worked part-time as a tutor but they still had enough money to get by. She is blond, cute and seems pretty conservative from what I´ve seen.

Anyway, despite being together since they were 16, they only got married when they were like 32. They had a daughter together. When she was pregnant with their daughter, he started an affair with a married woman (45F) 10 years his senior. This woman is also our coworker and like I said, she was also MARRIED with kids.

One year into the affair, 45F´s husband discovered the truth and asked for a divorce. A little while later, 35M also asks his wife 35F for a divorce. He has admitted to me that he was never in love with his wife and he only married her because they were together for so long and he felt it was the right thing to do. He was pressured by his parents to marry her too.

45F lost her job because of the affair (35M is related to the boss so he didn´t lose his job). However, they are still together 2 years later and they´re getting married this summer.

This man abandoned the mother of his child for an OLDER, MARRIED WOMAN WITH KIDS and now he´s marrying her too. And you wish to tell me that men are just simple creatures. From what I can tell, there was nothing wrong with the ex-wife, he just didn´t like her enough and she didn´t indulge his kinks. (I am not going to reveal how I found out, but I have reliable information that the guy is into pegging)

This happens all the time, many men leave and mistreat perfectly good women. Many men go for single mothers, women with tattoos and even pornstars. It´s not that these men have no other options, they are into this shit.
